A mosaic I did for my design class. It was a master study for one of my fav artist Caravaggio. It took me 3 whole days to complete it. Well, 4 days since I went back and add more pieces to fill in some awkward gaps. I really had a good time learning more about the different values of a composition and space. definitely space, because I like to use a lot of it. This is definitely a great piece to start on for a class or a hobby. What I did was pop in a movie and went to work. By time the movie was done I was halfway through the piece. Good luck, its best to exercise your fingers first.
